Q: usb powered hard drive not recognized

Dell Precision 4300 laptop T9300 2.5ghz processor running windows XP pro. Have a WD 400 passport external drive (powered through usb) that worked great for 6 months. Having problems recognizing the drive on usb port. Have a powered Hitachi drive that fine in the same port. Took WD passport and placed it on another computer and it works fine. When plugged into my laptop I can hear it fire up and the indicator light is on. WD troubleshot with me and we eliminated my drivers etc and same result. They warrantied the drive and new one has same issue. Tried a different cable. Dell troubleshot with me and diagnosed bad motherboard. Tech came to house and replaced motherboard with same results. Flashed bios and removed/installed drivers again same result. Drive will appear under device manager butI can't get to it. Part of my computer will lock up when drive in port and unfreeze when I pull it out. Also will see drive appear under my computer when removing usb cable. If I remove usb drivers and power up with WD plugged in occasionally I will be able to get to unit but it will freeze.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Okay I have a vista machine I built my self a few years ago. Recently the power supply died and I replaced it with a bigger better one. 600 watts instead of 400. Machine works great, however, now it seems that external harddrives that are not powered from an external power supply (2.5 inch western digitals I have) are not recognized at all when I plug them in. Doesn't show up in device manager, disk management or anything. Nothing happens when I plug them in. The lights blink on the drives but nobody is home. They work fine on every other machine I have. Now, I know the usb ports put out at least some power because my iphone mounts fine and charges, even my 5th gen ipod which is a hard drive, charges and mounts, all flash drives work.... Could it be the external western digitals are not getting "enough" power, do the usb ports get power from another line that i might have forgotten to plug in? I thought those ports were all powered from the main power line that plugs into the Mobo all the other functions of the computer seem to be just fine. I've tried all 6 usb ports on the back and get the same result.

Any suggestions on what to try? Am at a loss. the drives are passport western digitals, I have a 60 gig and 120 gig...

A:external hard drives not recognized/powered in vista

1.) What's the make and model of your power supply? It's possible that it's underpowered for your setup.
If the power supply is generic, how many 12V rails does it have, and how many amps are on each 12V rail?

2.) Have you tried the drives on a different computer? If that problem is solved after trying on another computer, it's definitely your PC hardware causing the issue.

Another issue with the laptop: the Passport drive is not recognized in the USB 3.0 connector on this laptop, but it is on the 2.0 connector. The USB cable I am using is the one that came with it, it has the blue part and sticker that says 3.0.

I was able to put this drive onto the laptop in the 3.0 connector yesterday but not anymore. I tried disable and re-enable the USB Controller but that didn't work.

When I plug it into the 3.0 connector, it actually does get power to the drive - the light comes on and I can hear it spin, its just that Windows 10 won't see it.

I have the T110, I can create the recovery discs in Windows but when I restart the computer and press F12 it shows no CD/DVD drive in the BIOS.

So I cannot restore from or boot from the external CD/DVD drive.


A:Satellite T110 - USB powered CD/DVD drive not recognized in BIOS


I don?t have the notebook in front of me but check the BIOS if you can find an option called ?USB legacy support?. If yes you have to enable this feature that your notebook can recognize the external drive.

Can you boot from an USB stick? I mean you can also create the recovery files on an USB stick so this would be also an option to restore factory settings.

I have a Sabrent 2.5" hard drive enclosure SBT-EKU25 that I am trying to use with USB on a Windows 7 laptop. The drive works but stops doing anything for several minutes at a time. There are no error messages, it just stops... no flashing or steady light. A minute or two later it picks up where it left off as though nothing has happened. It will then run fine again for several seconds and then it goes back to "sleep". I am trying to use the drive to backup files and it spends more time sleeping than doing anything else.

The drive enclosure does not come with any drivers and is supposed to be plug and play. I have checked the USB drivers and Windows says they are up to date. I have installed a 60Gb hard drive from an old laptop in it.

If i plug the the drive into the USB port on my Windows XP desktop it works fine.

What type of drive did you put in the enclosure? According to Sabrent's web site it only works with IDE drives.

My laptop HDD recently would not load windows. So i installed the OS on a different drive. Now, when i connect the old drive VIA USB 2.0toSATA it will not show up in My Computer. Disk Management will not show the drive either. The HDD is getting power, i can hear the disk spinning.

A:Hard Drive is powered, but does not show up.

Plug in and turn on the external USB hard drive
Right mouse click on My Computer
Left click on Manage
Left click on Device Manager
Expand the USB list
Find the USB device for your USB Hard Drive (the one that has no description)
Right mouse click - Uninstall
Turn off the external USB hard drive
Turn on the external USB hard drive and let it find and install the driver

Open 'Administration Tools', select 'Computer Management', click on 'Disk Management' and see if it can be seen here. If it does show here, chances are it doesn't have a drive letter assigned. If this is the case, right click on the drive, select "Change drive Letter...', and assign a drive letter to it.

If it was not seen there, go to 'Action' on the menu bar, click on 'Rescan Disks' and it should come up. If necessary assign a drive letter to as described above.

I tried replacing the hard drive on my Inspiron 9300 with a 200G drive.  The administrative computer tools in Windows XP recognized it, but the BIOS showed it as 130G or so.  I finally had to replace the drive with a smaller one.  I had the latest BIOS version.  Is there a BIOS fix that will allow the larger hard drive to be used?

I have a Compaq desktop with an
AMD Athlon 1.1GHZ
128MB of RAM
a 16mb TNT video card
and 60GB HDD

I tried to reformat the hard drive because I initially had a virus on it - so the only means was to format it. The first time I reinstalled it successfully with a copy of a WinXP Pro cd, that came with a dell laptop of mine. BIG MISTAKE-- the computer tripped out and was asking for authentication. No problme arised yet, windows xp installed, and authentication was the only thing that was being irritating.

I commensed to reformat the hard drive with nothing in it except the OS installed, with a different copy of WinXP that did not come with my dell laptop. In the middle of reformatting, however, about 51% complete, I powered down the computer because I thought it would not hurt the formatting process, so I could take it back to the owner's house and finish up the reformatting process there, and at the same time be able to hang out at their pool. the old idea of "kill two birds with one stone" or something. >_< I feel pretty stupid. I hope you guys don't chew me out now, but yeah.

So I tried to turn the computer on again later on to finish reformatting. I pressed the power button and everything seemed to go right, until nothing appeared on the monitor. the monitor stays black, with an orange 'standby' light as if the computer was on standby.

I use a Seagate USB 3.0 external hard drive to do automated system backups on a weekly basis, using both Windows and Acronis. I have always left this drive on all the time, even though I only use it weekly.

I have read where some users power their external hard drives off between backups.

Any recommendations on the best thing to do.......leave it on or turn it off?

Thanks in advance.........

A:Is It Best to Keep External Backup Hard Drive Powered Off

If you can disconnect this drive when backups are not happening, you increase your odds of not having any viri or malware hitting the ext HD. Other than that, disconnecting and powering off ext HD saves some wearNtear on said device.

I just rebuilt an old system using Windows 7 Home Premium after using WinXP pro for many years. The primary hard drive is WDC 150 Mg and Win7 is installed and updated to current with SP1. I dropped a second WDC hard drive in, formatted and was going to use it for a 2nd backup unit. Both of these are sata. Both hard drives are recognized by Disk Management but when I select Computer on the start menu ONLY the primary 150 Mg drive is recognized. If I plug in an external drive, both Computer and Disk Management recognizes the external drive. How do I have Win7 recognize my backup WDC drive so I can use it.

Had similarities on my pc.

Goto BIOS, there you have 4 options.

Primary Master
Secondary Master

Primary Slave
Secondary Slave

Set it as follows:

Primary Master -----> Main Boot HDD
Secondary Master -----> EMPTY

Primary Slave -----> CD/DVD RAM
Secondary Slave -----> Secondary backup HDD

So I have multiple external monitors. When I'm not usually all of them, I turn the ones off I don't need. I just press the power button on the front of the external monitor.

The problem is when I move my mouse, it will still go in the direction of the monitor that's off, causing me to lose my mouse, because I can't see it.

Is there anyway to prevent the computer from seeing the external monitor when I have it powered off? The external monitors are Dell U2414h monitors and the laptop is Lenovo x230 Tablet with Windows 7. The graphics card is intel hd graphics 4000. Thanks.

Hello All,

I just installed a new ASROCK FM2A88M Extreme4+ motherboard in my home PC last week. I have a CM Storm Quickfire Rapid i keyboard and a SteelSeries Rival mouse attached to the top two USB ports on the back of the motherboard:

Ever since I got this motherboard I have been having frequent, random issues with my Quickfire keyboard. What happens is, after a cold boot, about 20% of the time the keyboard does not light up and is not recognized by Windows. I have to either reboot or pull the USB plug and put it back in to get it to work. I have also tried switching around the USB ports (swapping which port the mouse and keyboard uses) but that doesn't seem to work. (I didn't try the other "lower" USB ports because I assumed that, due to the position of the ones I am using, that they are meant specifically to be used for keyboards and mice.)

The Quickfire keyboard is new as well but I did have it before I got the ASROCK motherboard and i don't recall having this issue (at least not frequently enough to remember) so I am leaning towards the conclusion that it's an issue with the ASROCK motherboard.

My first question is, is there a way in Windows 8.1 (event logs, device manager, etc.) to see what exactly is causing my keyboard to not be recognized all the time?

If you were to make an educated guess would you say it's an issue with the motherboard or the keyboard? (Note that the Quickfire keyboard did not come with any drivers or software, everything is done... Read more

I have a Dell Inspiron 1520 laptop. I have an image of the entire hard drive that I created when I first got the computer (using Acronis TrueImage), and I'd like to restore that image, returning the laptop back to that fresh, clean original state. I've done this two or three times before and it worked great each time.

But now there's a problem. Normally I would connect to the laptop a USB storage/backup drive that has the disk image, boot the laptop from a Rescue Media CD created by Acronis, then restore that disk image from the back-up drive onto the laptop's HDD.

When I tried it this time round, the laptop's HDD was not listed in TrueImage at all. I created a new rescue media disk, tried it again, and got the same result.

I then took the HDD out of the laptop, connected it to an adapter kit that let's you power up and plug in the drive via a USB port and external power supply, and tried the same procedure using my desktop to run the operation. Same result. The drive was not detected by Acronis.

The drive does not seem to spin up at all when it is connected.

** Keep in mind the drive still works when installed in the laptop -- it boots into Windows XP etc. **

When I plug the drive into my desktop, the drive does not show up in Disk Management (Start | Right-click My Computer | Manage | Disk Management). It doesn't show up in either of the two right-side windows. (so there's no way I know of to format it or d... Read more

I have a 1TB external storage drive that uses its own power supply and connects to my laptop via USB 2.0 cable. For months I've had absolutely no problem out of the device, until the computer randomly decided to forget the device was plugged in. Now I'm lucky to get the device to be recognized by the computer at all, and when it is recognized, if I try to move anything to/from the device, the connection is immediately severed from the computer.

I use this device for my backup as well as holding on to things I would rather not get rid of. All my drivers are up to date, I've done all the Power Management checking and unchecking that I've read from other threads found via Google search, and still it won't work correctly for me. Any advice?

A:Self-Powered External Storage not recognized/randomly disconnecting

Providing you have done all the power options to attack the problem from the OS end of things, then you must consider that the drive itself is the problem. This seems likely since the drive has worked fine in the past.

The first suspect would be the USB cable, the connector on either end, or the port on either end.

The second suspect would be the hard drives power supply. These do go bad. If it is not supplying proper power then the drive will fail to be recognized correctly.

Try the drive on another computer. If it exhibits the same behavior there then you can narrow it down to one of the two issues above.

A few months ago I setup my 2TB external hard drive as the designated drive to save new app, documents, programs, etc...It also acts as the drive where my desktop icons are stored. Everything has been working as it should until a few ago. When I start up are restart my computer none of my desktop icons show up and I have an error message that says there was a problem loading "desktop". The message also states to check and see if the files have been moved or insert a disk. Now that being said the only problem I am currently having is the desktop icons not loading properly. The external drive still shows up in "My Computer" and is still assigned as the designated drive to save information. I have no problems saving, moving, or viewing files from the external hard drive, but it is bothersome that my desktop icons and shortcuts do not appear. Is there a way to fix this problem without having to format the drive as there are several hundred Gb of data currently on the drive?

I used to have a cd rom and a cd burner master/slaved to my motherboard. a while ago that ide slot died, so i master/slaved my hard drive and my burner to the working ide slot.

a few days ago the computer crashed. i dont remember the exacy error but it no longer recognized the hard drive. when i tried to restart it brought me to the strike f1 to reboot/strike f2 for options screen. i assumed this meant that the hard drive was toast, but upon further inspection when trying to change the boot sequence in the BIOS it recognized the floppy drive but the the hard drive nor the cd drive were recognized. this lead me to believe that the second ide slot had now gone bad as well.

my brother has another dell dimension so i opened his up, removed his hard drive and replaced it with the questionable hard drive. i booted it and got Boot Failure : System Halted.

is this enough evidence of a hard drive failure? ive come to terms with it being time for a new computer but im still hoping everything on the hard drive can be recovered.

any opinions/suggestions?

A:Dell Dimension Hard Drive and CD Drive not recognized

Did you check that the Master/Slave jumpers were set correctly?
Moving a HD to another PC normally does NOT work, unless both PCs are identical in hardware. Put your 'old' HD as a slave in your brother's PC, boot up and see if you can access your old drive. Save whatever you can and burn onto CD/DVD.
Then go buy another PC, anything but Dell or eMachines!
Or better, if you have the know-how, build your own from components.

I have a Dell Dimension MCE 8400 that I ordered with a single drive. In retrospect I should have ordered it with 2 drives and without MCE but that is another discussion. I am wanting to install a new OEM WD Cavier SATA 160 with dual boot operating systems on the same drive but partitioned, XP Pro and MCE. I have installed the WD drive as the second drive (in position 1) and made a partition of 40 GB. The drive is seen by the system. I reboot the system and go into setup, disable the Maxtor SATA drive (one delivered with system and in position 0) change the boot order so it boots from CD, save the changes. I boot the system with the Win XP Pro CD, and in the FDD I have WD SATA drivers. The system boots, I hit F6 and it looks as though it is reading the SATA controller drivers. Needless to say the system doesn't recognize that a hard drive is present. Please help!!!!! If anyone has any ideas or suggestions it would be greatly appreciated.

I'm having a problem in that my second hard drive is NOT recognized more than it IS. I have a Western Digital as my main hard drive, and a Samsung as my secondary. I have swapped out the cables, so it does not seem to be a cable problem. I have the Western Digital DataLifeguard Tools, which I'm not sure if I can get it to help, as it only wants to help with Western Digital drives. The first drive is set up as Master, the 2nd is set up as Slave, not Cable Select (when I can get it to "see" the 2nd hard drive, it cannot read the data on it if it is in Cable Select)

I'm running Windows XP Home SP2. As a side note, I did have to do a repair, but used a new disk, which upgraded from SP1 to SP2, but that was after the problem occurred.

Any suggestions?

A:Hard Drive Not Recognized

Is it detected in the BIOS? Is it detected in Device Manager as a drive? If yes then you likely just need to initialize, partition, format, and assign it a drive letter through Disk Management: http://windows.microsoft.com/en-ca/...n#create-format-hard-disk-partition=windows-7

Also, your power supply should have more than one SATA power cable. What power supply do you have?
I'd use the adapter on the optical drive and give the hard drive the SATA connector from the PSU instead.

Hi from glenaurora

I have recently installed a 2nd 500GB HD and it will not work on my desktop. It's use is for extra capacity only. The OS is Windows XP home. It is installed via the shared ribbon cable with the original 160GB HD. The ribbon cable is plugged into the secondary mother board connector(this is the way it's always been) The 500GB HD(New) is connected to power and the grey 40 pin connector and the 160GB HD(Old) connected to the black 40 pin connector The old HD is set to "master" and the new HD is set to "slave" When both are connected I get a message upon boot up telling me there is no OS installed. When I disconnect the 500GB HD from power and the ribbon cable everything works fine. Could this be a matter of formatting the new HD or does it need to be connected seperately to the primary ribbon cable connector on the mother board? It only lists HD :C and at no time lists the other HD.

A:New hard drive not recognized

It might just be an issue with boot priorities in BIOS. Head into BIOS and check the boot order.

Ideally you want it to be the following:

1st: CD/DVD drive
2nd: Your 160GB hard drive with the OS installed.
3rd: Can be anything really.

A:Hard Drive not recognized

Maybe it's your data cable. I mean I had a similar problem before. First I thought it was my hard drive, but after ruling that out, I finally found that I needed a new data cable.

If your system has a spare data cable (like your CD drive, if connected through another cable on your other IDE port) test this one on your hard drive.

You could also test your hard drive on a friend's PC to rule out hard drive malfunction.

My external hard drive (EHD) is not being recognized by several computers that run on Windows XP and XP Professional. The EHD is Western Digital Series 1 USB 2.0 (Old USB 2.0) – Model Number WD1200B05-RNN. It is just over 2 years old and is out of warranty.

I’ve done some reading online forums such as this where users have had similar problems, but I didn’t see any solutions – or, any that I understood, so I ask that if people have suggestions, to guide me through it step-by-step.

It was working a few days ago. The other day, I was doing a file search on it and it stopped responding in mid-search, so I started the search again, and it stopped responding again in mid-search. After that, the computer won’t even recognize it as a separate drive, although the bottom right of screen shows a symbol that there is an external HD plugged in. Windows XP detects that I plugged in the external hard drive and the icon “Safely remove device” appears too in the tool bar. However, I cannot see the drive in “My Computer.” I’ve tried to plug it into 2 other PCs including my laptop, and the same thing happens: it isn’t seen under “My Computer” but the icon appears on the taskbar. I’ve tried to unplug it & re-plug & restart the computer, but nothing. I’ve tried installing the driver again and restarting, to no avail.

Well it certainly sounds like the drive has died.

If it helps, CompUSA is selling a Hitachi 200Gb HDD for $70 after mail-in rebates this week. Better hurry. It ends tomorrow I think.

Now as far as trying to recover data..There is one technique (which sounds really weird but works for some people). Kind of a last resort technique when all else fails and you don't want to spend big money on data recovery.

Put the old HDD in a ziplock bag and stick it in the freezer for a few hours. The cold sometimes helps the HDD work for a little bit of time. You would then take the chilled HDD to a working PC and install it as a slave so you can hopefully copy as much data as possible off it.

Good luck.

I'm not new to computers by any means (Bachelors Degree) but very rusty on troubleshooting hardware issues.

I have Win XP Professional Edition on an AMD motherboard with Athlon Processor and 2GB RAM. Everything seemed fine until recently. I have noticed that out of the blue, my hard drive will disappear and the screen goes to a black screen with white lettering saying something about no hard drive found. I will reboot and go into bios settings and set it to boot from my SATA drive, however sometimes it does not show my hard drive there. I have to completely shut down the pc and wait an hour or so then turn back on and it boots Windows just fine. This is aggravating. I have purchased a new Power Supply (850w), I have replaced the thermal paste on the CPU due to a vibration and extreme heat coming from back of tower (this did reduce the heat issue). It almost seems like the pc is overheating or something and shutting down the hard drive. Is this possible or just me over thinking? I use canned air frequently on all my pc's to keep them dust free and clean.

I hope this wasn't just babble but if you need further info to assist in troubleshooting, please let me know.

I would test the hard drive with a bootable CD version (ie DOS version) of drive makers' diagnostic software. I'm not saying the drive is failing, just that it can't be ruled out without testing it. You can use SeaTools for DOS: http://www.seagate.com/support/downloads/seatools/

or Hitachi Drive Fitness Test: http://www.hgst.com/support/index-files/simpletech-legacy-downloads#DFT

In either case the download is an ISO CD-image. Create a CD from this with IMGBurn: http://www.filehippo.com/download_imgburn/

You could try:

Go to Device Manager:

Click Start, then right click My Computer, select Manage. Go to Device Manager, then under Disk Drives, right click the External Hard Drive and go to Properties, go to the Power Management tab, then uncheck the option to "Allow the computer to turn off this device to save power"

However, the computer may turn back on from standby/sleep if the hard drive requires any power at all..

Trying to install a hard drive, and it will not recognize it. Keep getting "Primary Master hard disk failure" over and over.

This computer was infected by a virus a while back. It was never quite right, so decided to clear out the hard drive, and start from scratch. However, the BIOS will not auto detect the hard drive that was on it, nor any other hard drive. Have tried 3 different ones.

The cables are tight, and connected correctly.

Any ideas on what to do?

A:Hard Drive Not Recognized

Read other 10 answers

Well I am back again sooner than I expected. I am running Win XP Home (upgraded Win98). I currently have two hard drives-14gig with the OS on it and a 60gig for everything else. Both are IDE.

I purchased a Maxtor 120gig sata hard drive and my intentions were to eliminate the 14gig as the boot drive by replacing it with the new one. I didn't have an onboard connection so I installed a PCI controller which the device manager says is working properly.

I figured no sweat, just install the new drive, format, partition and copy the boot drive to the new one using MaxBlast3. The problem is I can't get the computer to recognize the new hard drive when it is hooked up so I cannot do squat.

Anyone got any input that might help me?

It doesn't show up in the bios or My Computer.

Thanks in advance!

I've recently completed building my own system. I am using an Intel DG33FBC board with a WD Raptor 74G SATA Drive. The drive does show in the BIOS, however when I try to run XP the drive is not recognized. I have tried hitting F6 during the installation for 3rd party drivers, but still no luck. Also, when I boot the machine without XP, I get a message that no bootable drives are recognized. I find this strange, especially because the drive is recognized in the BIOS. Any suggestions?

Hello and welcome to TSG!

If you plug a different drive into the channel and it works ok then yes, I would suspect the drive. Pardon me for mentioning the obvious but: have you checked the drive to ensure that it is jumpered correctly?

My Western Digital MyBook 1.5 GB has recently stopped working. I spins for about 20 seconds, then stops. It is not recognized in windows explorer, but it is recognized in device manager and disk management.

Under disk management it says that it has 2047.35 GB unallocated space.
It also says the disk is unknown and not intitalized. When trying
to intitalize the drive, it says "The media is write protected".

I have tried swapping usb cables, running safe mode, and freezing it.

Any help would be amazing! Thanks!

When a drive/parttition can be seen in the Device Manager and Disk Management, but does not show up in My Computer, most of the time it is only the partition table that is either missing or corrupt.

In such a situation my advice will be to try and fix it with the freeware Test Disk. The program runs in a command window and may be a little daunting to a new user but if one diligently goes through the step by step procedure given in the online documentation, it shouldn't be difficult. Download and documentation: TestDisk - CGSecurity.

HELP! I have a 40GB HD that I want to use as an external drive. I have it hooked up through a USB port and an independent power supply. My problem is this: I wanted to format it and followed directions from a Google site. They told me to right click on My Computer, use the Manage option, go to Drive Manager and then get rid of the partion on the drive. When I did this, the drive dissappeared from "My Computer" AND the Drive Manager although it still shows up in my Device Manager. What do I need to do so that my XP home edition will again recognize the drive? I sure would appreciate any help.

hey, i am trying to backup files and programs to an external hard drive. and a messages comes up saying "one of the USB devices attached to this pc has malfunctioned and windows does not recognize it. can anyone help? thanks

A:Hard drive not recognized

Usually this means there is a hardware issue.
Can you try the external HDD in another PC and see if the issue occurs there?

If not, then you may want to reformat it and then move it back to your PC and see if the problem happens again... if it does, then you may have a USB issue on your machine.
Try another USB port if so, and if that doesn't do it, try reinstalling your USB device drivers for your PC.

Though 9 out of 10 times this is an issue with the device which may be remedied by moving to another computer, or the device itself is actually damaged/defective.

Hard Drive Not Recognized i followed this tutorial http://www.youtube.com/watch?v=Jclt_ylFWXs but i obviously done it wrong and wiped my hard drive and had to buy a new one. I still have the old one what i am wondering is can i take the hard drive out when my system is running and put the old one in and fix it with drivers. It's a Western digital hard drive if that makes any difference.
Thank you in advance.

hi there

well on the motherboard you should have a few sata connectors so why don't you plug the drive(leave the new drive in you don't need to take it out) that you replaced back in(WARNING please unplug the pc from the mains lead pull the cable from the pc and press the on/off button for 5-10 seconds to discharge any power in the machine, and touch a piece of clear metal on the pc case to earth yourself to rid any harmful static before doing any work on your pc) and we will go from there ok. i take it its a internal drive? could you post your machine specs to help with diagnosing problems in the forums please.

Hello all, I have a severe problem and hope someone can help me.

It started last night with my computer off and unplugged. My 160gig external drive was still plugged in and on when it was accidentally unplugged. I plugged it back in, and a minute later heard 2 clicks...i shut it off immediately.

turned it back on an hour later and the computer. no clicks, but it the drive didnt show up in "my computer". it did show up in the device manager as working properly. But when looking at volume information in properties it shows as unreadable. It also doesnt show up in disk management.

I have tried several downloaded programs and most see the drive and show it as corrupted partition. They also show the drive as far larger than it is (like 2 terrabyte) and show it as 1 head 1 sector.

I am lost as to what to try next. I hope someone can help me.

Welcome to TechSpot

Your unplugging corrupted the file-system of that HD.
You could try and take it out of the case, set it to slave and stick it in a PC, connect it to an IDE-cable.
Then hunt around for various Data-recovery programs. Try and D/L this one from TechSpot's DL-area: http://www.techspot.com/download201.html

I have a Dell Dimension XPS T350 computer that does not recognize my hard drive. It's not a hard drive problem because I have tried other hard drives that work in my other computers. The ribbon cable is connected tightly. The jumper is set correctly.(Master) I've checked the bios settings. When I type "C:" a message comes up saying "Invalid Drive Specification". Also, when I type FDISK , a message comes up saying "No FIxed Disks Present". I had the same problem with my Compaq Deskpro 2000. I attempted to take out the cmos battery by prying it out but it was difficult to remove so I left it alone so as not to create more problems. I tried rebooting again and I was able to get to the "C" prompt, although the "D" drive wasn't appearing when I clicked on "MY Computer". I had to reinstall Windows 98SE. But for my Dell computer I took the battery out and put it back in and the hard drive is still not recognized. Any suggestions as to the problem with my hard drive not being recognized?

A:hard drive not recognized

Is this a new drive? Did the problem start all of a sudden?

Does the BIOS recognize the drive?

Take another look at the jumper. Some require a jumper only when on a cable with another drive, and some require a different position of the jumper if there is another drive on the same IDE cable. Try removing the jumper altogether.
